This is x^3+x^2+1=-x in math terms, where x is the number. So x^3+x^2+x+1=0. We can write this: x^2(x+1)+(x+1)=(x^2+1)(x+1)=0. The only real solution is x+1=0, so x=-1.
Hopefully that makes sense
Let the age of Jay be x years, so age of Jay's father is 2x years .
After 20 years,
Jay's age will be 
And Jay's father age will be 
But at that time, jay's age will be

So we have

Cross multiplication

Therefore Jay's age is 20 years and Jay's Father's age is 40 years .
